Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Suspension made a 'thunking' noise while driving over bumps. I took it into the dealer and was told the R. rear tensioner leaf spring worn or was worn and needed replacement. I never got a straight answer as to why, bad metal or what? I've never towed anything and have never had any heavy loads in the bed causing over compression of the leaf springs. Truck has always seemed to lean to one side and looks lower than factory height. Dealer fixed under warranty. It now seems to be making a similar noise but from the front suspension area while driving over speed bumps and into driveways. I have to verify this and get it back into the dealership for more work...and try to get answers.
